This is the latest in a series of measures the president has announced in a renewed clampdown on extremism.

Madrassas have been in the spotlight after one of the London bombers was reported to have studied at one.

The problem with this approach?

But the BBC’s Aamer Ahmed Khan says it is not clear what effect these measures will have on extremism as the more militant students work at unregulated madrassas that have survived previous crackdowns.

The fallout?

In a recent visit to a Lahore madrassa, our correspondent Aamer Ahmed Khan found foreign students visibly uncomfortable with the links being drawn by the media between terrorism and religious education.

The students said they were there simply to learn and were “more disappointed than angry” at the terror links.
